I am using the onCellEdited extension function in a column with all none values.
print "oldValue = ",oldValue print "newValue = ",newValue
If I click on a cell but do not change anything it still changes the value to 0.0.
The oldValue is None and the newValue is 0.0.
How can I prevent 0.0 from being entered. I only want 0 if they enter it.
